Electrical drive with permanent magnet excitation for nearly wattless generation of moments of torsion and any necessary carrying forces has a four-pole mechanical winding outside and a two-pole carrying winding inside.

摘要

A four-pole mechanical winding (11) on the outside has three outer strands (13-15). A two-pole carrying winding (12) on the inside has three inner strands (16-18). These two separate winding systems fit in grooves in multiple layers for forming torque and carrying force. Electromagnetic and permanent magnet pole structures generate a magnetic flux in air gaps for a rotor run with a reluctance section.
